Paper Abstract

New dynamical aspects have been investigated in the flexoelectrically excited angular waves of a nematic liquid crystal by means of a modulation ellipsometry technique. At low frequency (f < 1 Hz) the gradient flexoelectric torque dominates and causes an out of phase electrooptical effect. At high frequency (f > 1 kHz), the surface friction is responsible for a new dynamical behavior. The surface viscosity is evaluated to be 3 (DOT) 10-5 erg(DOT)s/cm2.
